Petroleum project challenges
Petroleum Project Challenges

Petroleum environmental projects from upstream to downstream have different needs:

  • Baseline samples should be taken prior to and after drilling

  • Accidental spills during drilling may require sampling and analysis

  • Hydraulic fracturing is now under great scrutiny from a number of angles: water supply, fluid composition, and disposal or re-use of frac fluids

  • Unconventional resources such as coalbed and shale gases often involve the production of a large amount of water, which must be managed, and often discharge monitoring reports must be provided to regulators

  • Transportation activities, such as by pipeline and truck, can result in spills with environmental impact

  • Refining has its own set of environmental issues, such as monitoring of discharges to nearby groundwater and surface water

Petroleum data challenges
Petroleum Data Challenges

Petroleum environmental data provides special challenges:

  • Handling on non-detected results

  • Multiple dilutions to maintain a linear instrument response

  • Comparison to multiple, and often complex, regulatory limits and target levels

  • Special handling of non-aqueous phase liquid data

  • Potentially large amounts of data

  • Inconsistent reporting of hydrocarbon ranges

  • Often complex site geology

Baseline Sampling

  • Program requirement types

    • Voluntary - Example: Pennsylvania, NY

    • Mandatory - Examples: COGCC, Ohio

  • Timing

    • Pre-drilling

    • Post-drilling

  • Reporting requirements

    • Agency

    • Operator

Cogcc rule 609
COGCC Rule 609

  • Rule 609, and modifications to Rule 318A, were published by the Colorado Oil and Gas Conservation Commission (COGCC) in February, 2013, for permits issued after May 1, 2013

  • These rules made Colorado the first state in the country to require pre- and post-drilling sampling of water sources near new oil and gas wells

  • Consultants, labs, and software vendors have cooperated with COGCC to update the transfer of data to COGCC’s database using COGCC’s new XML or an Excel format

Rule 609 sample requirements
Rule 609 Sample Requirements

  • Sampling required for new oil and gas wells, multi-site wells, and dedicated injection wells

  • Installing of monitoring wells is not required

  • Samples must be collected from up to four water sources within a half mile of proposed well location

  • One pre-drill sample required with 12 months prior to setting conductor pipe

  • Two post-drill samples required, one 6-12 months and one 5-6 years after drilling

  • Data must be made publicly available on the COGCC website

  • Rule 318A (Wattenberg Area) has slightly different requirements (one sample per quarter, one post-drill)

Baseline sampling and reporting steps
Baseline Sampling and Reporting Steps

  • Determine locations

  • Obtain landowner permission

  • Take samples and field measurements

  • Enter locations in COGCC website

  • Obtain the Facility ID

  • Import field measurements

  • Obtain and import lab data

  • Review data

  • Export to COGCC format, with Facility ID

  • Upload to the COGCC website

  • Review submission online

www.geotech.com


Cogcc facility information
COGCC Facility Information

  • The first step on the state website is to upload the location

  • The location is then given a Facility ID

  • This should be recorded and added to the lab and field data before upload

  • This can also be used on the COGCC website to retrieve and view the data

www.geotech.com


Typical sample location
Typical Sample Location

  • Typical compliance costs:

    • Sampling: $2,500

    • Lab analysis: $500 - 600

    • Isotopic analysis, if needed: $300 - 400 more

Future direction and discussion
Future Direction and Discussion

  • For COGCC, perhaps a way to download the Facility IDs and Sample IDs

  • More data retrieval options from website

  • Expansion to other states

  • Use by the public

  • Use in litigation

  • Other issues?
